BRICK WALL.

To all whomfz't may concern:

Be it known that I, ERNs'r EVALD O'r'rnns'rRoM, a subject of the King of Sweden, re-' siding at Stockholm, Sweden, have invented new and useful Improvements in Brick Walls, of which'the following is a specification.

The present invention relates to a brick wall consisting essentially of bricks in two different groups, of which the one group the first groupin section shows two re cumbent bricks and between them erect bricks, and the other group, which is of the same height as the first group, consists of erect bricks. This brick wall can be performed in such a way that its respective main layers in section of the wall show one of each of the two groups of bricks, with the groups placed alternately on different sides of the wall in layers lying over one another. Further, bricks standing edgewise can be arranged between one or both kinds of brickgroups. 7

By constructing a brick wall in accordance with the present invention, the advantage is attained that, owing to the fact that most of the bricks are placed erect, a greater strength of brickwork per net area is obtained than in an ordinary wall with recumbent bricks, as has been shown by experiments. In explanation of this fact it be observed that the walls in question have, per height meter of wall, a far smaller number of joints than an ordinary wall, and it is a well-known fact that a large quantity of mortar has a very injurious effect on the strength of the brickwork. Moreover, by this construction it is possible in a simple and practical manner to produce a brick wall with lengthy reinforcements of wood, ferroconcrete, or the like within it, which wall in the case of heavy loads has many advantages over a wall of bricks solely. The present wall also combines with the desirable slen- Specification of Letters Patent.

formed in accordance with the present in vention with reinforcing beams of wood. Figure 1 shows the wall in elevation, Fig. 2 in vertical section along the line 22 in Fig. 1, Fig. 3 in horizontal section along the line 33 in Fig. 1, and Fig. 4:. in horizontal section alongthe line 44.-'in Fig. 1.

The wall shown consists 'of two walls 1 edgewise (on short-edge) in the transverse direction of the wall, alternately, looking in the longitudinal direction of the wall, with a group of four bricks 10, 11, 12, 13 arranged in the longitudinal direction of the wall, of which two 10, 11 are placed edgewise (on long-edge) side by side. (if necessary, with. some space 14;), looking in the transverse direction of the wall, between two recumbent bricks 12, 13, besides which the single brick 41- in the one layer 3 is straight above or under, respectively, the four-group 10, ll, 12, 13 in the other layer 7. As is evident from Fig. 2, the wall shows in section two groups of bricks, the one (the first group) l0, 11, 12, 13, and the other the group 5, 6, which are placed alternately on different sides of the wall inlayers lying above one another. These two groups of bricks form between them channels 15. In

the example shown there occur also, horizontally and vertically passing, reinforcing I beams 16 or 17 of wood, which are united with one another into a framework. For the horizontal reinforcing beams 16 there are lengthwise channels, which have been obtained simply by omitting the bricks 11 and by replacing the bricks 8, 9 with a single brick 18 placed edgewise (on short-edge), looking in the longitudinal direction of the wall; and, at the same time, by replacing the bricks 8, 9, as stated, with the brick 18, vertical channels have been obtained for the vertical reinforcing beams 17.

The detailed parts in the wall shown may of course be varied in many ways, provided only that the characteristic feature of the invention is retained. In a complete condibricks in two different groups, one group of which in section shows two recumbent bricks and between them erect bricks, and

the other group of the same height as the first group and consisting of erect bricks, the respective main layers of the wall 1n section showing the groups placed in alternate layerson different sides of the wall, with one of each of the two groups lying over one another. 7

3. A brick wall as stated in claim 1, characterized by the fact that between the kinds ofbrick-groups there are placed bricks standing edgewise.

4:. A brick wall as stated in claim 1, characterized by the fact that in the layers at different heights of the wall are arranged lengthwise channels, in which elongated reinforcing members are placed.

5. A brick wall as stated in claim. 1, characterized by the fact that vertical channels are arranged at a suitable distance from one another, looking in the longitudinaldr rection of the-wall, in which channels elongated reinforcing members are placed.

6. A brick wall as stated in claim 4, characterized by the fact that the lengthwise channels are formed by the omission of the inner erect brick in the first group and by placing the bricks standing edgew se between the first brick-groups. in such wise that they do not present any obstruction in the said channels.

7 A brick wall as stated in claim 5, characterized by the fact that at the places where the vertical channels are to be formed, the bricks which stand edgewise between the first groups of bricks are placed in the longitudinal direction of the wall.

In testimony whereof I have signed my name to this s ecification.
